I suspect the last day of flowering (pollen shedding) in the common garden was yesterday. I won't be totally certain until the snow falls, but here's the full story... Dwight observed eight heads on Friday the 29th. Two of them were shedding pollen and each had two immature florets. Today, I observed them all again. Neither of the of the two normal heads shed pollen. One head was obviously done and the other (40-943.5-yel) has one immature floret. I suspect that that one immature floret will not mature, but I may be wrong.
Six heads are still in the bud/dud stage. They haven't yet started to flower and they don't look like they will. But, I may be wrong.
I will report on the flowering status and post a complete flowering schedule within a few days. I will also recap the final week of team Echinacea--we had an awesome finale. But first I need to catch up on sleep and harvest some heads tomorrow. The forecast is for winds 25 - 30 mph and gusts to 41 mph.
